This applicationis a division of an application numbered 576,925, filed July 24, 1922, for-Letters Patent of the United States.

This invention relates to cash registers and the like, and more particularly to machines of the type shown and described 1n Letters Patent ofthe UnitedStates No. 1,230,- 864, issuedl to W. A. Chryst, on June 26, 1917, and Letters` Patentof the United `States Nos. 1,242,170 and 1,394,256, issued to 1F. li. Fuller on Oct. 9, 1917 and Oct. 1S, 1921, respectively. y

, The principal` object of the'present invention is to provide ardevice for removing the ink yand impression rollers used with such a machine as shown `in the above mentioned patents, as a unitfrom the machine. Y

Another object kis to `enable thegopera'tor sin'iultaneously to move the'inking and 1mpression rollers away7 from the type carrying rollersinorderto facilitate the insertion of the receipt or check strip between. them, previous to an operation of the machine.

lil/lith these and incidental ob]ects in view, the invention consists of certain novel features of construction and combinations of parts,vthe essential elements of which are set Vforth in appended claims and a preferred -form of embodiment of which is hereinafter describedv with reference to the drawings which accompany andv form part of this specification.

Of said figures:

In machines 'of the above specified type the check strip, which is a continuous paper stripY from which the'receipts issued by the machine are printed and severed, passes'between two ypairs yof electro and feedingv rollers in order to receive aportion ofthe print- -d matter carried thereby. lt is of course lnecessary in order to take an impression from these inipression rollers, that the. i'mpression rollers for each ofthem be so situated that the check Ipaper will bev firmly pressedagainst the type on the electrorollers. This, makes it necessary, without using` the present invention, to j insert the check paper at one sideof the device and operate the machine 'several times until thepaper has been fed by. these rollers far enough tor come tothe positionin which it is severed and issuech However, with the use of tliepresent inventionin connection with this mechanism. a small lever is moved, which 'forces the electro4 and impression rollers apart a suffi cient distance so that. the check strip can easily :be passed therebetween and broughtto fthe severing position -without 'havinglto 'operate the machine. It is evidentthatthis is a great convenience whenit becomes necessaryto place anew roll of check paper in the machine, V

v If at anytime it was desired to change the electrorollers, or to put fresh ,ink on the inkingf rollers, it .was necessary` Ato take these rollers out one at a time, in order to accomplish the above results. lVith the use of the present invention, however', the two impression rollers and the two hiking rollers are all carriedin a removable frame. This frame is normally latched in its correct position in the machine, but when it is desired to have access tothe rollers above mentioned all-that itk is necessary to do is to release a catch on. the front ofthe carriage, as. willbe herein- Lifter described, and withdraw all -of the above n'xentioned rollers from the machine as a unit. i

A short and Avery general description of someofthe parts vshown in Fig. 1 will now be p'iven for the-'purpose of .giving a correct understanding of the. relation betweenthe removable carriage and the surrounding parts of the printing mechanism. i

i This maehineis .adapted to print upon three d iiferent mediums; first, the detail strip;

ysecond, the Acheclr strip; land third, an i.n

serted slip. The printing upon the first two of these mediums is done by repeated impressions of a platen 25 carried by a platen frame 26 pivoted at 27, with a series of type carriers 28 loosely mounted upon a tube 29 supported by a rod 30, as is well known in machines of this type. These type carriers 28 are differentially positioned under the control of the amount levers in this particular case, or by any other form of manipulative devices, and are differentially set in accordance with the positioning of the said devices. The inserted slip receives its impression from a similar group of type wheels 31 located directly below the type wheels 28 and set up in the same manner. The impression is taken by means of a platen 32 carried by a U-shaped member S3 supported by two arms 84 pivoted on a shaft 35. At, the appropriate time this platen is given a rapid upward movement and will strike the inserted strip with sutlicient force to take an impression from the lower type wheels 31.

The detail strip 36 is carried by a storage roll 37 and passes about a roller 38, then the platen member 26, back toward the left about a roller 39 and is wound upon a` receiving roll 40, shown in Fig. 1. Suitable means is provided for feeding the detail strip yone step or space upon each operation of the machine. This means, however, is not shown herein.

The check paper, or check strip, as it will be hereinafter called, is carried by a large storage roll 42, and from this roll passes between guides 43, between an electroroller 44 and an impression roller 45, then between the impression roller 46 and a second electroroller 47, across a block 48, where it is either perforated and then severed, or simply severed, depending on the character of the receipt to be issued, and finally beneath the upper platen where it will receive its final impression from the type wheels 28.

The electrorollers 44 and 47 are rotated in opposite directions and cooperate with their' respective impression rollers 45 and 46 in order to feed the strip across the knife block and under the upper platen. This feeding movement is given the electrorollers in the following manner. A. shaft 50, which is the main drive shaft of the printing' mechanism and which receives one complete ceunter-clockwise revolution on each operation of the machine, carries thereon a disk 5l which supports two pins 52. These pins cooperate with notches formed in a Geneva plate 53 and are so positioned that they will rotate said plate two-fifths of a revolution upon every operation of the shaft 50. Rigidly connected to the Geneva plate 53 is a gear 54 which meshes with a pinion 55 loosely mounted on a shaft 56. Fast to the pinion 55 is a gear 57, which in turn meshes with a gear 58 engaging with a gear 59 fast to the electreroller 44. The gear 59 also meshes with a gear 60 fastto the electroroller 47. It can be seen from the above that when the shaft 50, and therefore the disk 5l, are given one completel counter-clockwise revolution, the Geneva plate 53 and gear 54 will be moved in a clockwise direction. This movement of the gear 54 will move the pinion 55 and the gear 57 in a counter-clockwise direction, and this counter-clockwise movement of the gear 57 will be transmitted by the gear 58 to the gear 59, which is fast to the electroroller 44, thereby rotating this roller in a counter-clockwise direction and the other electroroller 47, due to the engagement of the gear 60 with the gear 49, will be moved in a clockwise direction. The movement of these two electrorollers, in combination with their impression rollers, will feed the check strip toward the right a sufficient distance to bring it to its correct position for printing and severance.

An inking ribbon 62 extends from an inking roller 63 about a plurality of anti-friction rollers 64 in such a manner as to bring it to position to ink the type carriers 2S and 31 in order that an impression may be taken by the upper and lower platens, as above described.

Impression cmd nk roll carriage.

A more detailed description will now be given of the carriage which carries the impression and ink rolls and which is removable as a unit from the machine.

A plate 68 and a plate 69, best shown in F 3 and 4, are secured together by rods 70 and 7l. These plates are supported by long studs 72 and 73 (Fig. 1) mounted in the printer frame and projec ing into tubes 74 and 75 which carry the impression rolls 45 and 46. Loose on each rod 70 and 71 is a pairl of arms 76 and 77 which are made integral by a yoke 78. Rotatably mounted on rods 94 and 95 supported in the arms 76 and 77 are ink rollers 79 and 8() adapted to ink the electrorollers 44 and 47, which are carried by long studs Sl and 82 projectingr from the printer frame. The ink rollers are maintained in contact with the electroreliers by means of coiled springs 190 surrounding the rods 70 and 7l. These studs 8l and have grooves cnt near their endsI and project through holes 83 and S4 respee tively in plate 68, and are adalited to he engaged by semi-circular portions 85 of a L Ye 86 pivoted at S7 to the plate 68. thereby locking said vimpression roll carriage in its position on the machine, as shown in section in Fig. 1. The carriage is adapted to be removed from the machine for the purpose of cleaning and inking the-ink rolls 79 and 80. It is shown detached from the machine in Figs. 2, 3 and 4.

TWhen it is desired to remove the carriage it is necessary to rock the plate'SG clockwise to the Vposition shown in Fig. 4i means orn apinchflever c'oi'n'prisiiig an e'a'r`88 formed 'bylplateo and having ahooled portion .90 "adapted tov latch over a `pin v91 'carried by plate't' and hold` the plate "86 in itsy on position.l The hool'ed portion 90 is vheldin .engagement,With,the r`pin, Qlby a spring 92 'i f emoy'e V'the ink 'rollers the plateSG has two Yeo surfaces l'92'and ilflcooperating with theie'ndsfofth'e ink roller supporting rodsl .SME antilla Whiclrprojeet through elongated slotsfile and?? ycutin, the plate l68.
